SPECIFICATION forming part of Letters Patent No. 734,639, dated July 28, 190 3. Application filed October 29, i902 Serial No. 129,190. (No model.)

To all whom, it may concern:

Be it known that I, PAUL WALLENSTEIN a citizen of the United States, and a residentiof Venus, county of Knox, and State of Nebraska, have invented a new. and useful Improvement in Machines for Turning Down Spindles for Wagon-Axles, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions. I

My invention relates to hand-operated devices for turning down worn wagon or buggy spindles.

The object of my saidinventionis a provision-of means whereby such turning down of the spindle may be efiected without removing the axle from the vehicle to which it is attached.

Said invention consists of means hereinafter fully described, and specifically set forth in the claims.

The annexed drawings and the following description set forth in detail certain mechanism embodying the invention, such dismechanical forms in whichthe principle of trating same mounted upon the vehiole-axle.-

the invention may be used.

In said annexed drawings, Figure I represents a front elevation, partly broken away,

of a device embodying my invention, illus- Fig. IIrepresents a vertical axial cross-sectional view of the front of the frame, show-1 ing the forming-surface for guiding the cutting-tool, the spindle-axis and the inner portions of the cutting device being also therein shown, together with means for holding such cutting device firm; and Fig. III represents a vertical section of the device, taken upon a plane indicated by the line? .3,.Fig..I, and viewed as indicated by thearrow in said figure.

A frame A is formed with a shank a, which is adapted to be secured to the under side of the axle B by two clamps G 6, provided with hand-screws cc, which'bear against the under surface of the shank, whereby the latter,

as will be'readily understood, may be se- The end of said curely fastened to the axle. shank is provided with hand-screw a, which .is provided or formed with two small arms a ct, which carry upon their inner ends a barrel or", provided with an internal frustoconicalforming-surface a, which is coaxial with the bearings a and a the inclination of the said surface to the said axis being equal to that of the bearing-surface upon the spindle-axis which it'is desired to impart to such spindle. The inner end of said barrel is provided with an apertureo coaxial with the bearings 0t and a and the forming-s11 rface a. This aperture is of a diameter such as to freely admit the axle-spindle and is' surrounded by the neck 0. projecting from the end of the barrel, having three set-screws a passing therethrough, as shown, whereby the spindle may be adjusted relatively to the barrel-axis, as will be readily understood.

A threaded shaft D is journaled in the bearings a and a its outer end being pro- 'vided with an end crank (I, screwed thereto.

The inner end of said shaft is provided with an arm D, pivoted upon the carrying-piece d, so as to be capable of oscillation toward and from the barrel-axis. The inner end of The shaft is formed with an axial bore 11 in which slides a rod E, Whose inner end is provided with an internally-threaded portion 6, which is adapted to be screwed upon the threaded end I), of the axial spindle b.

Two extensible supports F F. have their sliding members ff mounted upon the frame A, preferably upon the shank and that portion immediately below the barreL. These supports carry the weight of the device and the vehicle during the operationof turning. A convenient form of support is that shown in the drawings, in which the lower end of the sliding member f is provided with a series of transverse holes and extends into the interior of the hollow base f, which is. provided with a transversely-removable bolt f which may be caused to pass through each one of the holes in the arm f, as will be readily understood.

In applying the above-described device the frame is mounted upon the axis and the latter is supported by the supports F, the clamps 0 being left loose and the axle-spindle b projecting into the barrel a For adjustment the set-screws a are now turned so as to cause the spindle-axis to intersect the middle of the aperture a in the end of the barrel. The hand-screw a is now turned in the required direction, so as to incline the frame upon said screws as a fulcrum, thereby causing the axis of the spindle to become coaxial with the axis of the barrel. It is thus seen that the angular relationship of the frame, and hence of the barrel-axis, may be changed to bring the said spindle into coaxial relationship with the barrel. This is often necessary, for the reason that the spindles frequently become bent under usage. The rod E is slid toward the axle, and its end is screwed upon the end of the spindle, as shown in ,Fig. II. The tool d having been adjusted to give the required diameter to the spindle when finished and the clamps tightened to secure the frame firmly to the axle, the device is ready for operation. This is effected by turning the crank d, whereby the shaft is antomatically fed forward and the tool guided by the roller d in contact with the framesurface a. The rod E acts as a support and guide for the inner end of the shaft D, Whereby it prevents said inner end from springing, and so impairing the action of the cuttingtool. The rod E being readily removable, other rods may be substituted therefor having. internallythreaded ends conforming with various sizes of the threaded axial ends, as will be readily understood, so that the device may be used for various sizes of spindles. To cause. the wheel-hub bearings to receive the newly-turned axle-spindle, such hub is provided with a bushing having the required diameter.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any one of the following claims or the equivalent of such'stated means be employed.

I therefore particularly point out and distinctly claim as my invention- 1.
